2 The Wish List Save money via AMR automated meter reads Meter is the endpoint Dominated by one-way technology: - Drive-by - Powerline (PLC) Improve reading / billing accuracy Identify outages Daily data All that and more: 1. AMI Advanced Metering Infrastructure 2. DR Demand Response 3. DA Distribution Automation 4. DG Distributed Generation Two-way, real-time, end-to-end communications: - monitor & control / remote upgrades / opt-in & out Multiple communications options; network evolution Multiple resource metering: electric, water, gas Multi-application functionality: - identify outages / prioritize / restoration alerts Dynamic pricing / load shedding Data integration with MDM Surgical deployment Improve billing, regulatory & conservation 15-minute data / on-demand reads

3 Building a Future Friendly Network AMI projects once defined by type of communication system: Utilities had to pick a basic flavor: - Wireless: Fixed RF / RF Mesh WiFi / WiMAX - Wired IP: Fiber, Ethernet, BPL - PLC: Powerline Carrier - Mobile: Drive-by / Walk-by Some better suited for specific deployments Driving Change Same choices Combine flavors Impractical / impossible to mix & match

4 All-or-Nothing Too Risky Utilities challenged to select a communications platform that provides a long term solution Too risky to make a significant capital investment without clarity on uptake, cost recovery, or regulatory framework Infrastructure investments expected to last multiple decades

6 The Three Smart Grid (SG) /AMI Driver Areas DRIVERS OF SMART GRID/AMI

7 Five Key Questions 1. What does the system need to do now? 2. How can this best be achieved? 3. Is there sufficient capacity for data intensive applications and increased network traffic? 4. How easily can the system adapt to new and additional needs in the future? 5. How cost effective is its adaptability?

8 Flexibility to match investment and benefit

9 The Upshot Building a Smart Grid is a series of projects that must interoperate eventually Communications network is the critical choice Support the multi-applications that will make the smart grid Avoid the need to retool the network later: Business case for subsequent projects becomes much harder to achieve if fundamental technology change-out required The system should provide a simple and cost-effective migration path to future technologies Hybrid network allows utilities to mix-and-match communications options today and in the future: Leverage existing infrastructure options and delay commitment to new standards until they are ratified and commercially proven

10 Pulaski Electric System Municipal electric utility South-central Tennessee TVA partner Urban & rural mix 500 square miles service territory 14,000 electric customers 1200 miles of distribution line 125 miles of fiber 5800 homes passed / 31% with FTTP

11 Hybrid Network Hybrid backbone using FTTP in city of Pulaski & wireless 220 MHz to rural customers Drives additional & ongoing value from FTTP network Simultaneous use for Smart Grid and triple-play media Redundant network, easy WAN collector change out Surgical deployment ; prioritize high need / high return customers Scalable & flexible

12 Best of Both Worlds Overlay PES Energize FTTH network (urban) RF 220 MHz extends range to rural customers 220 MHz WAN collector options enabled PES to start with either IP or RF Two networks co-exist within AMI network 900 MHz LAN; connections to meters and other devices Surgical deployment to fast track high value accts

13 Evolution :: RF to FTTP Energize Energize Energize

14 Wired & Wireless Networks FTTH WAN Collector 220 MHz WAN Collector Urban deployment Communicates with multiple LAN devices: - smart meters, smart thermostats, etc Rural deployment Long-range, two-way communications backbone in tough terrain

Pulaski Results Drives additional value from FTTH; accelerates ROI Simultaneous use of FTTH for Smart Grid and triple-play media Extend Smart Grid functionality to outlying rural areas at minimal

15 Pulaski Results Drives additional value from FTTH; accelerates ROI Simultaneous use of FTTH for Smart Grid and triple-play media Extend Smart Grid functionality to outlying rural areas at minimal cost via RF End-to-end WAN/LAN/HAN Redundant, flexibly deployed and scalable; easy WAN collector change out Expand FTTH when / as needed Surgical deployment; prioritize high-need, high value customers

16 Why Fiber? Broadband ideally suited for transporting real-time information dynamically and reliably Future-proof network can handle increasing bandwidth demands and layered applications without costly network upgrades Real-time responsiveness to commands; instantaneous event alarms such as outages Many backhaul options have lags of secs; others delay communication for hours or days speed needed for tightly coordinated load shedding and distribution automation applications No recurring communication costs

17 Why Municipal Broadband? Municipalities established in the business of providing electric services Citizens used to government provided utility services Utility back-office systems in place for billing & customer service Utility may be in process of installing broadband organic evolution Customers prepared to buy additional services from a utility Leverage Broadband Triple Play Media 1.High speed Internet 2.Voice Over IP 3. Hi Def TV Homerun Network 4.AMI / DR / DA

18 Smart Grid / Smart Infrastructure Broadband offers security and reliability Small meter data packets require minimum bandwidth Leverage existing infrastructure; minimal costs for subsequent deployments and follow-on applications: Share network with other municipal services: electric / water / gas Lifespan estimated at 50-plus years Accelerate ROI Homerun Network for triple-play media and Smart Grid Benefits No surprise rate changes or disruptions during emergencies Costs remain consistent; no outsourced cellular or paging networks No recurring line leasing fees Unlimited reading No seat licenses

19 State of the Nation - Broadband Fast Facts 88 municipalities operating FTTP / FTTH; 31 of 50 states 25% increase over 2008 most at small & mid-sized cities Only a handful using broadband for Smart Grid Source: Broadband Properties: 2010 Broadband Census

20 Fiber-Enabled Grids EPB Chattanooga:: Tennessee Fastest municipal fiber in the US; 1 GHz, 200x the national average Virtually unlimited scalability to support Demand Response and HAN devices Smart Grid efficiency justifies broadband implementation Central Indiana Power :: Indiana First coop to merge with local telco Streamline business processes Avoids cost & complexity of two networks Summerside Public Utilities :: Prince Edward Island Speed & bandwidth for advanced load control Monitor & manage wind generated power Support in-home energy storage Attract high tech businesses

21 Crystal Ball Considerations Wise to over-build your communications network. The backbone network will be required to work harder, faster and carry a bigger data payload Capacity to grow without fear of congestion: - AMI, DR, DA, DG An inflexible infrastructure will limit a utility s ability to evolve A good fit today may hamstring future functionality Don t get caught in situation where the life of the asset falls short of the projected payback period Open standards for interoperability with future applications Timing: change priorities as objectives shift Crystal Ball Considerations Hybrid network allows a utility to hedge its bet and move in the direction that is most likely to succeed Mix and match current systems with those adopted down the road: - RF 220 MHz / 900 MHz - FTTH - WiFi / WiMAX - LTE - inet - Cellular

22 GM Lessons Learned Address metering and C&I ratios first Legacy issues Management team sensitivity Employment Education/Training Commitment PR/Messaging Customer engagement
